The Bernal Cut groups existing and proposed green spaces in the Bernal/Glen Park/Mission neighborhoods. Their current plan is to add rain gardens in their targeted region, which includes concrete removal to add a bioretention swale and the design and construction of a traffic bule, which will serve as a rain garden and provide a traffic calming component. Our work included outlining the drainage sheds feeding into the potential gardens, calculating their areas, and estimating the location and sizes of the new rain gardens.
